Q. What different types of GeForce card are available and what are the differences between them?
The following list is with the cheapest and slowest cards first, and the most expensive and fastest cards last.
GeForce 256 SDR - Runs at 120mhz core / 166mhz memory.
GeForce 256 DDR - The same as a GeForce 256 SDR except it uses DDR memory.
GeForce2 MX - May be SDR or DDR, but they are both roughly the same speed because with the MX DDR memory has to run in 64-bit mode as opposed to SDR which runs at 128-bit mode. Runs at 175mhz core / 166mhz memory and does not require a fan on the heatsink.
GeForce2 GTS (DDR) - Runs at 200mhz core / 166mhz memory.
GeForce2 Pro (DDR) - The same as a GeForce2 GTS, except it runs at 200mhz core / 200mhz memory.
GeForce2 Ultra (DDR) - The same as a GeForce2 GTS, except it runs at 250mhz core / 230mhz memory.
GeForce3 - Runs at 200mhz core / 230mhz memory.
The GeForce2 series uses a 0.18 micron manufacturing process instead of the 0.22 micron used in the previous process, meaning less power consumption and heat production. All cards in the series have a second generation T&L engine, can render two textures per pixel instead of just one, have the NSR (NVIDIA Shading Rasterizer) and an HDVP (High Definition Video Processor) for better DVD and HDTV support.
The GeForce2 MX supports 2 monitor outputs for TwinView (two video outputs to two monitors, or one monitor and a flat screen display or TV) on the same card) and Digital Vibrance Control. It has only 2 texture pipelines instead of 4 on the GeForce or GeForce2 GTS, and a less advanced HDVP without support for some high-end modes.
The GeForce3 uses 0.15 micron manufacturing process. It is a new generation of chip, much faster than the GeForce2, fully DirectX 8.0 compliant, has the nfiniteFX Engine engine, providing support for vertex and pixel shaders, Lightspeed Memory Architecture for improved memory bandwidth, and High-Resolution Antialiasing (HRAA) support for faster antialiasing support in the form of Quincunx antialiasing. It also supports Digital Vibrance Control.
